Patented July i3, 1920.

To all 'Lo/tom t may concern.'

Be it known that l, HENRY hi. NunaiuAiQQR, a citizen of the United States, residing at Canton, in the county of Stark and State of Uhio, have invented a new and useful Hay-Carrier, of which the following is a specification.

This invention relates to hay carriers and has more especial reference to cross draft hay carriers or that class of carriers in which the elevating rope leads from the carrier in a direction substantially at a right angle to the track along which the carrier is adapted to move.

rlhe object of the invention is to provide a hay carrier of the character mentioned with a spring pressed bolt controlled by a lever and arranged to be automatically released when the desired load is attached to the elevating rope locking the elevating rope against movement and locking the sheave.

Another object is to provide a hay carrier in which a spring pressed bolt is moved into position to hold the parts in the loading position by means of the operation of the elevating rope.

With these objects in view the invention consists in the novel construction and arrangement of parts, hereinafter described, illustrated in the accompanying drawings, an d particularly pointed out in the appended claims, it being understood that various changes in the form, proportions, size and minor details of construction may be made withinthe scope of the appended claims7 without departing from the spirit or sacriicing any of the advantages of the invention.

lThe invention thus set forth in general terms is illustrated in the accompanying drawings forming part hereof, in which- Figure l is a side elevation of a carrier embodying the invention, mounted upon a track showing` the parts in the unlocked or loading position, the near side of the frame being removed and parts4 broken away to more vfully disclose the construction. y.

Fig. 3, a side elevation of the carrier, the inner side of the frame being removed and parts being broken away to more fully disclose the construction, the parts being shown in the locked position assumed when the load is being transported along the track;

Fig. ll, a side elevation of the carrier show ing the parts in the unlocked or loading position; and

lig. 5, a side elevation upon a smaller scale of the carrier showing the rope fall.

A. practical embodiment of the invention is disclosed in the accompanying drawings, forming a part of this specification in which similar numerals of reference indicate corresponding pa ts throughout the several views.

rllhe track l upon which the carrier is adapted to run may be of any suitable or well known form and is suspended fron] any substantial support such as the rafters of a barn. rlhe main frame of thecarrier is suspended upon the truck frame 2, which is provided at its ends with the rotatably mounted traveling wheels 3 adapted to run upon the track.

The main carrier frame is formed of two sides d and 5, preferably stamped from sheet metal, connected to each other and held in spaced relation. Strips 6 are attached to the side frames in any approved manner and extend upwardly beyond the frames, the upper extremities of said strips being connected to the head 7, which is carried in the truck frame 2. ln this way it will be seen that the carrier with its load is suspended from four traveling wheels, two being arranged at the front and two at the rear; In the lower portion of the main frame and at a point substantially beneath the center of the track is located the main sheave axle 8, which extends transversely from one side frame to the other and upon which is rotatably mounted the main sheave 9.V This sheave is preferably of considerable diameter to lighten the draft as much as possible and facilitate the Voperation of the carrier.

Pivotally connected to the side frames l and 5 upona transverse bearing having its axis at 10 is the rope locking lever 11comprising two similar spaced members joined together by means of the bolts l2 and 13. The rope locking lever extends outwardly to one4 side of the main frame and is provided with a downwardly depending portion 14 in lwhich are carried the rollers 15 and 16,

mounted upon the Vbolts l2. The sheave brake 17 is pivotally mounted upon a suitable axis 18 adjacent the main sheave 9.

The rope grip l9is preferably of the form shown and provided with a serrated surface 2O upon the side adjacent the rope and is pivotally mounted between the side trames upon the bolt 10. The outer extremity oi' the rope gripy is pivoted at 13 between the spaced side members ot the role locking lever and a pair vof spaced nected at their upper extremities tomthe bolt i3, the lower extremities of said links being connected to the housing il bolt 2l; is. pass-ed through the lower extremities of the links 22 and through the outer extremities of a pair et spa-ced "links 'which are p ivotally connected at 26 to the side tl'anges. A bolt 27 is slidabl'y mounted throi'mh the housino 23 and orovided with e.

n .l noch i u i coll spring 2Swhich bears against a fixed collar 29 upon the bolt, said bolt being arranged to'` enter the aperture 30 in the plete l'uponthe main 'frame when the parts are in the unlocked position as shown in 1.

A lever 32 is pivrtal'ly mounted upon the bolt 2l, the upper extremity oit said lever hrung provided' with a forked end 33, which `vstraddles the 'bolt 27 :and receives the thrust of said bolt by engagement with the collar 291 [The outer extremity oit-saidv lever car ries a suitable eye or link Edito which the extremity of the elevating Vrope 35` is attached. v

ln reevmg the carrier one end ot the ele- 'vating rope is connected to the eye 34;, "either by knotting or by use of a device such as the rope clamp 36'. 'Extending from said eye'the rope passes downward and through the'lifting head or headset the fork, sling or other hay engagino device, and then upwardly from said hay engaging device and over the main sheave 9. and then outwardly Y beneath the rope grip'l) and between the i rollers and lo upon the rope'locking lever.

From this point the elevating rope extends downwardly at an angleA to the side ot' the ba-rn' in which the carrier is mounted and passes over the usual' pulley mounted upon thebarn wall and commonly known as the purlin pulley. This of courseis common in all crossl draft hay carriers'and it is unnecessary 'to illustrate this pulley inthe present application. .v Y i It will be understood that the carrier is varranged to beI moved laterally upon the other weight is attachedfto the end ot the rope'and. the` other rope passes over a suitable pulley. at theV other side of the barn4 and extends.. downwardly. This rope is usually/referred*toas the shift rope or conoownwardly Vdepending links 22 are pivotally con-V movement ol the elevating.rope.`

veyer rope and is used to move the hay carrier upon the track, the sand bag acting as a counter-weight to. nieve. the carrier back to the original position when the shift rope is released. rl`his is the usual arrangement of shift rope and has no relation to this invention excepting that some means should be 4provided i'or moving the carrier upongthe track. p

rllhe operation of a hay carrier embodying the invention is as'lfollows: The parts being in the loading position as illustrated in lio. 1, it will be noted that the rope locking lever is in the raised position and the extremity of the bolt 2? is located through the aperture 3,0 in the main trame-ot the carrier, thus through the links 22 holding therope locking lever in the raised positionv Vand maintaining the rope vgrip in unlocked position so that the .tall of the elevating rope may be brought down to the pointJ ot attachment ot the load.V l/Vhenthe load is attached and the elevating team which is attached to the lreevend ot thefelevating rope,'is driven forward drawing the elevating rope forwardly, the load will be raised towardthe carrier, the angle at which the elevating rope is located `from the main sheave of the carrier to the purlin pulley causing thev rope locking lever to beheld in the upward or 'unlocked position, allow ing the main sheave to rotate. lWhen the load has been carried up to the carrier and the elevating team stopped, theweight oi the load will be sufficient to pull the lever 32 into the position shown in Fig. 3 releasing the bolt 27 from the aperture 30m the main trame Yand moving Vthe parts into the position shown in Fig. 3. It will be` noted that when the parts are in this position the rope grip 19 is held intight engagement with the rope pressing the rope firmly against the brake 17 and, holding the` brake tightly against the marin sheave, thus` locking the sheave vagainst Yrotation and preventingany p twill be seenV that instead of mere-ly grippingA the rope as is usual in hay carriers the `main sheave itself islocked against rotation. i .T he load will thus be sustained during the travel of the carrier along the trackrto the 'place of discharge of the load andin actuntil the carrier .is returned in thensual manner to the loading point. Theshift or conveyor ropeV is. then operated to move the carrier along the track until it reaches: the propel" position over the mow. The slinger fork is then tripped in theusual manner`-allow1ng the hay to drop into the mowfand theshift rope is operated in theI opposite direction, moving the carrier back along the track to the initial or loading point` The elevating rope is ythen givensa quick pull straightening the said rope from the main sheave to thepurlin pulley, raising the rope loking lever and moving the parts into the unlocked position as shown in VFig. Il. rlhe rope grip is thus held in the unlocked position and the brake is released allowing the Inain sheave to he rotated so that the iall of the elevating rope niay be brought down to the point ot' attachment oi" the load.
